2.4 - Programmable Operating Mode

Pre-configured programs can be loaded from the calibrator memory, enabling
the programmable operating mode. The temperature programmed values of the cavity
are used directly, with no need to enter the set point.
The display shows STEPn beside the cavity temperature set point value in the
programmable mode. The number of the program is indicated by n. Using the keys

and , the programmed values of temperature set point are changed. The numeric
keypad continues available for manual selection of the black body cavity temperature in
the same way of the manual operating mode.
The automatic scan over the programmed temperatures is implemented by
defining the stabilization time of the thermo-element in the black body cavity.

The key
message STEPn gives place to 0s and the calibrator waits for the stabilization time
configured from 1 to 9 minutes, by the keys 1 to 9. The automatic scan is disabled by

pressing key again.
A countdown of the stabilization time is only started when the cavity temperature
reaches the programmed temperature and stabilizes within a range of approximately
 0.20 ºC. At this time the buzzer beeps, in case it is configured to YES.
